Which stink more sugargliders or ferrets?

I have had a sugar glider before and could handle there stench but the thing is it was hard to clean the cage cuz it was homeade and my sugar glider would not let me wash them so i was wonder since it would be easier to get all the ferret stuff clean and i was planning on giving them that special stuff you put in the water for there oils might help make them not stink as bad as my sugar gliders did
